I think that's found in the commentaries to the Chinese Agamas. I believe Ven. Analayo mentions it in his treatise on Satipatthana. I have a copy at home. I'll check when I get a moment.

Sadly I can't seem to find the source. I know I have heard that before, however. From what I recall, somewhere in the Chinese Agamas there is a truncated version of the 32 parts of the body contemplation. The "oozing orifices" was one of the parts they used. I believe Bhikkhu Bodhi also mentions this truncated contemplation in one of his Majjihima Nikaya lectures. Again, a source eludes me right now.

@SumindaSirinathS.Dharmasena: have you emailed Mr. Piya Tan for an answer? He is most helpful (and so are you).

"A boil,' monks, is another word for this body composed of the four properties, born of mother & father, fed on rice & porridge, subject to inconstancy, rubbing & massaging, breaking-up & disintegrating. It has nine openings, nine un-lanced heads. Whatever would ooze out from it would be an uncleanliness oozing out, a stench oozing out, a disgust oozing out. Whatever would be discharged from it would be an uncleanliness discharging, a stench discharging, a disgust discharging. For that reason, you should become disenchanted with this body."

Thanks for the effort but this seams a bit tangential to what I was looking for. I modified the question for more clarity.

Unfortunately I don't have the Sariputrabhidharma source and so won't be of much help there. Anyway, the oozing orifices description should be pretty consistent across schools. Personally, I'd go to the sutta discourses first and then use the abhidhamma if needed for any further analysis..

“Again, bhikkhus, as though he were to see a corpse thrown aside in a charnel ground, one, two, or three days dead, bloated, livid, and oozing matter, a bhikkhu compares this same body with it thus: ‘This body too is of the same nature, it will be like that, it is not exempt from that fate.’

(MN 10 - Bodhi, Trans)

The Visuddhimagga explains the phrase (festering = oozing):

The festering: what is trickling with pus in broken places is festering (vipubba).
What is festering is the same as “the festering” (vipubbaka). Or alternatively,
what is festering (vipubba) is vile (kucchita) because of repulsiveness, thus it is
“the festering” (vipubbaka). This is a term for a corpse in that particular state.
